With the Netzsch STA 409 PC it is possible to measure
weight change (as a result of evaporation,
decomposition, chemical reaction, etc.), simultaneously
with heat flow as a function of time or temperature. This
way weight change events can be coupled and
compared directly to endo-/exothermic events in one
measurement run. By connecting a Mass Spectrometer,
evolved gasses can be identified or known gaseous
components can be followed.
TG analysis can be used to analyze tire rubber chemistry,
determine the carbon black content of a master batch,
determine the composition of a cosmetic, understand
thermal stability of pharmaceuticals, find the triggering
temperature of a blowing agent, determine the melting
temperature of alloy solders, find the vapor pressure
curve for lubricants, etc. DSC heat flow measurements
are used for the simultaneous detection of thermal
events.

TGA 850 Mettler Toledo
Thermogravimetry (TGA) is a technique that
measures the change in weight of a sample as it is
heated, cooled or held at constant temperature.
Its main use is to characterize materials with
regard to their composition and thermal stability.
Application areas include plastics, elastomers and
thermosets, mineral
compounds and ceramics as well as a wide range
of analyses in the chemical and pharmaceutical
industries.
Examples of thermal events and processes that
can be determined by TGA:
• Quantitative content analysis (moisture, fillers, polymer content, materials, etc.)
• Adsorption and desorption of gases
• Kinetics of decomposition processes
• Sublimation, evaporation and vaporization
• Oxidation reactions and oxidation stability
• Sorption and desorption of moisture
• Pseudopolymorphism
• Determination of Curie temperatures

substantial volume change can be measured in a large temperature range.

Praying Mantis (DRIFT) - temperature and atmosphere
Spectrum library: FDM (>26.000 spectra)
Infrared spectroscopy uses the fact that molecules
absorb specific frequencies that are characteristic
of their structure. These absorptions are resonant
frequencies, i.e. the frequency of the absorbed
radiation matches the transition energy of the
bond or group that vibrates. The infrared
spectrum of a sample is recorded by passing a
beam of infrared light through the sample.
Examination of the transmitted light reveals how
much energy was absorbed at each frequency (or
wavelength). Alternatively, the whole wavelength
range is measured at once using a Fourier
transform instrument and then a transmittance or
absorbance spectrum is generated using a
dedicated procedure. Analysis of the position,
shape and intensity of peaks in this spectrum
reveals details about the molecular structure of
the sample.
Our Midac M4000 FTIR provides a
full range of resolutions from 2cm–1
for routine analysis up to 0.5cm–1
for high resolution work, such as
multicomponent analysis. Several
different kinds of cells and detectors
enable us to measure a several types
of sample material. With the
extended library we can identify
materials (inorganics, adhesives, oils,
polymers, dyes, cosmetics, drugs,
etc.) within seconds.
